ZTR will supply 16 single phase transformers to HPP Sayano-Sushenskaya

ZTR will supply 16 single phase transformers rated for power 533 MVA voltage 500 kV to HPP Sayano-Sushenskaya (Yenisei river, RF). Equipment will be installed instead of transformers manufactured by ZTR that have been I operation more than for 20 years. For modification of transformer equipment HPP Sayano-Sushenskaya has announced tender among the first-rate companies of engineering industry. Due to the professional competence and quality of supplied production, PJSC “Zaporozhtransformator” has won the tender.

Within the preparation of contract conclusion, ZTR suggested to customer two types of transformers: three phase transformer rated for power 800 MVA voltage 500 kV and single phase transformer rated for power 533 MVA voltage 500 kV. Customer has chosen the second type of the transformer. Such kind of selection was stipulated by economical efficiency, possibilities not to make significant changes and maximum keeping of construction parameters at station.

Contract on supply of 16 single phase transformers was signed October 16, 2010. One more condition of a contract, in addition to requirements of high efficiency and reliability of equipment, was the provision of seismic stability of equipment: transformer stability to earthquake in 8 points according to Richter scale. In order to perform these requirements, construction of separate units was reinforced; appropriate decisions were approved by special conclusions.

The developer of PJSC “ZTR” applied innovation technique within the production of single phase transformers. «Optic fiber sensors that allow to measure the temperature of equipment are installed on the equipment, – tell the head of designing office Nataliya Bespalova. – The powerful monitoring and diagnostics system is put into operation. Detail analyze of the transformer in any moment is provided by similar system.“

At present 6 single phase transformers are supplied to HPP Sayano-Sushenskaya. The other equipment is under testing. The Customer should receive it to the end of the current year.
